$asc returns the Unicode code point number for the character (or first character of the string).
Synopsis[edit]
$asc(<char|string>)
Switches[edit]
None
Parameters[edit]
charThis would be any special character, letter, or number for which you wish to retrieve the Unicode code point. Only codepoints 1-65535 are valid. For codepoints above 65535, it instead returns the first UTF-8 surrogate. If the parameter is a string, the 1st character of the string is used as the 'char'. If parameter is a string, it uses only the 1st character of that string.
- Note: mIRC v6.35 and earlier only support codepoints 1-255
Examples[edit]
Echo the Unicode code point for the letters A and a to the active window
//echo -a A is $asc(A) and a is $asc(a)
Echo the Unicode code point for the number 7 to the active window
//echo -a $asc(7)
Echo the Unicode codepoint for the lower-case 'm' because that's the first character of the string. //echo -a $asc(mIRC) Retrieve the codepoint for any input: alias Get_Asc { //var %a $input(type or paste any character/string or alt-NNN or alt-0NNN value,e) | echo -a the codepoint for %a is $asc(%a) } The C parameter for the token identifiers uses the same codepoint number output by $asc(): //echo -a mIRC.exe is located in folder $gettok($mircexe,-2,$asc(\))
Unicode codepoint 128286 has UTF-8 Encoding of 0xF0 0x9F 0x94 0x9F and UTF-16 Encoding of 0xD83D 0xDD1F. Translated to decimal, these numbers are UTF-8 240 159 148 159 and UTF-16 55357 56607. If you change the font to "Segoe UI Symbol" which supports viewing this emoji, you'll see a number 10 inside a box. The numbers in the displayed message are the same even if your Font doesn't correctly display the emoji. This shows that $asc sees the only the UTF-8 surrogates of the string. //bset &v 1 240 159 148 159 | var %a $bvar(&v,1-).text | echo -a %a is $asc($mid(%a,1)) $asc($mid(%a,2))
